Compression Ratio for Type R Head on LS block with ITR Pistons?

Thinking about building a 2nd motor for my car and was wondering what compression would be if I took an LS block .025 overbore and went with ITR pistons and stock USDM Type R head?

Thanks, all

10.829:1 is what I come up with. All you are doing is adding 2 mm of stroke to it...
